Phosphatidylserine is a phospholipid found in high concentrations in the brain. It plays a crucial role in cell membrane structure and function, helping to maintain cellular integrity and support communication between cells. This compound is essential for various brain functions, including memory, learning, and mood regulation. Supplementing with phosphatidylserine has been studied for its potential benefits in cognitive health, particularly in older adults experiencing age-related cognitive decline. It may help improve memory, attention, and overall mental performance, making it a popular choice for those looking to support brain health.
